FAN-BLOWER.

SPECIFICATION forming part of Letters Patent N 0. 374,093, dated November 29, 1887.

Application filed March 9, 1886. Serial No. 194,617. (No model.)

,To all whom it may concern.-

Be it known that 'I, WRIGHT, D. SMI'rEuof Detroit, county of Wayne, State of Michigan, have invented a new and useful Improvement in Fan-Blowers; and I declare the following to be a full, clear,'and exact descriptionof the same, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying IO drawings, which form apart of this specification.

My invention consists of the combinations of devices and appliances hereinafter specified, and more particularlypointed out in the '15 claims, and has for its object certain new and useful Improvements in fan or blower cases. In the accompanying drawings, Figure 1 is a side elevation of a device embodying my invention. Fig. 2 is a separate view of an ad justable bracket and bearing. Fig. 3 is a front elevation of two blower-cases adj ustably connected together. Fig. 4 is a separate view. in section. I

A represents a fan or, blower case. a is its 2 5 discharge-outlet.

B represents supports engaged with said case, having legs or feet b, located at all four quarters of the circumference of the case and projected therefrom in such'a manner that the case may be locatedupon any of said feet, so as to direct the discharge in either direction horizontally or in either direction vertically, as may be required, -the discharge-outlet being extended through the floor, in case it is de- 3 5 sired to direct the discharge downward. By constructing the case in this manner with legs or feet at all four quarters it is evidentthat the case maybe readily located in any desired position, or may have its position changed to 0 direct its discharge in a different direction should it bedesired said feet being preferably provided with bolt-orifices b,whereby it may be engaged upon the bed or floor.

0 represents a driving-shaft; O, a drivingpulley located thereon.

D represents an adjustable yoke or bracket for supporting the driving shaft and pulley,

consisting of one or more annular rims, D D, whereby said yoke or bracket may be engaged upon the fan or blower case, said rims being the driving-pulley. D represents a similar constructed with a series of elongated slots, d, the construction being such that the bracket may be adjusted in its engagement with the case so as to occupy any desired position.

D represents a series of arms, which may be conveniently four in number, engaged with said rim or rims at one or both ends, as may be desired.

In Figs. 1 and 4, where a single case is used, the bracket may consist of a single rim provided with a series of arms engaged therewith, as shown, the oppositeends of said arms engaged with a sleeve, D", in which is located an adjustable box or bearing, 0 at one end of 5 sleeve containing an adjustable box or bearing-sleeve engaged with the adjacent rim, D, by means of spokes d.

When it is desired to engage two fan-cases together, as shown in Fig. 3, the arms D instead of being engaged directly with the sleeve D*, as shown in Figs. 1 and 4, are engaged with an additional rim, D, as shown in Figs. 2-and 3, the sleeve D being engaged with the rim D by spokes d, the only difference between the bracket for a single case, or for the union of two cases, being that in the former instance the arms D are continued, as shown in dotted lines, Fig. 2, the spokes d forming an integral part thereof, the intermediate sections or portions of the rim D being unnecessary. In the latter instance the arms D are united at both ends with rims D D to form an adjustable engagement with each of the cases. The brackets are engaged with the case or cases by means of bolts d extending through said elongated slots (1. By this construction, when it is desired to locate a case to direct its discharge in any given direction by loosening the nuts upon said bolts, it is evident that the yoke may be adjusted in its engagement with the case, so that the power may be belted upon the drive-pulley 0 without interference by the arms D The sleeves D D? are preferably adjustably engaged with the drivingshaft also,which may be accomplished by providing the shaft with the bearings O for each of said sleeves, said bearings constructed with an annular slot, as shown at c, Fig. 4, the

- sleeve being engaged therewith by setscrews 10o 0. By this construction itis obvious that the bracket or yoke may be adj usted relative to the hearing, by means of said set-screws 0, without altering the engagement of the rim D with the case. In many instances where the arms would not interfere with the belting this adjustment might be all that would be necessary without altering the engagement of the bracket with the case; but where the arms of the bracket come in the way of the belt the bracket would require to be loosened from the case and turned until the arms clear the belt. Then by loosening up the set-screws the hearing may be turned in the sleeves, so as to bring the oil-cup in a vertical position, the oil-cup E being preferably located upon the bearing, as shown. Thus, when the adjustment of the bearing alone would not be snl'iicient, the adjustment of the bracket relative to the case and the bearing relative to the bracket. both together,would effectually accomplish the desired object. I11 this manner the adjustment desired may be readily effected, either where one or two blowers are employed.

\Vhat I claim is 1. The combination, with a fan or blower cas ing, ofa bracket composed of two annular portions, each having elongated slots (1, arms rigidly connecting said annull,and sleeves formed with or rigidly connected to radial arms mounted upon or formed integral with the annuli, substantially as described.

2. Thecombination, with a pair of fan or blower cases, of an intermediate bracket having at each end an attaching-plate provided with elongated slots to receive the attachingbolts, a sleeve at each end rigidly connected to the end plate, and set-screws tapped through said sleeve to engage a bearing for ashaft which enters both casings, snbstantiallyas described.

3. The combination, with a pair of fan or blower cases, A, of an intermediate bracket having end plates, D D each provided with longitudinal slots (2, radial arms (Z sleeves D D and setscrews 0, bearings C, having grooves c, and a shaft supported in said bearings, substantially as described.

4. The combination, with the casing A, of

the bracket D, having annuli D D provided v with elongated slots (1, the connecting-arms D, radial arms d", sleeves D D, and setserews c, the bearings C", and shaft 0, substantially as described.

5. The combination, with a pair of fan or blower cases, of an intermediate connectingbracket having slotted ends, supports upon the sides of said cases, and bolts for connecting said supports with the slots in the ends of the bracket, whereby each fan-case may be turned to direct its discharge in either direction verticallyor in either direction horizontally, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.
